[0014] Beneficial effects
[0015] The present utility model provides a gear structure that is convenient for lubrication. It has the following beneficial effects:
[0016] 1. For this gear structure that is convenient for lubrication, during use, unscrew the sealing cover, add lubricating oil into the oil storage bin through the oil inlet hole. Then, the lubricating oil flows into the oil discharge bin through the oil discharge hole. Next, the gear body starts to rotate. Under the action of centrifugal force and the tension spring, the ball valve moves towards the middle of the diamond-shaped oil outlet hole. At this time, the lubricating oil enters the diamond-shaped oil outlet hole and flows to the meshing surface until it lubricates the meshing surface, reducing the wear of the gear body. When the gear body stops rotating, under the pulling of the tension spring, the ball valve resets and blocks the diamond-shaped oil outlet hole, thereby reducing the waste of lubricating oil.
